I was under the impression that the only way to get flouride out of drinking was distillation. I apparently was wrong. According to about.com reverse osmosis will also remove flouride.

In the same article I found out that black and red tea come from two different types of plants, but both leaves naturally contain high amounts of fluorine.

The drinking water flouridation issue is still unsettled. I would enjoy entertaining your comments and queries on this issue.
